Seed enhancement methods are applied to eliminate or decrease adverse environmental stresses effects and increase seed germination rate and vigor of rangeland plants. The aim of this study was to assess different methods of seed coating effects on germination speed of Onobrychis sativa at different sowing depths and soil moisture levels. The experiment was conducted at growth chamber to apply a...
abstract persian shallot (moseer) belongs to alliaceae family, is a perennial medicinal and industrial edible alliums in iran. very little information is available about different aspects of this species particularly on its agronomical production. in order to determine optimum sowing date and plant density in persian shallot, an experiment was conducted as split plot based on complete randomize...
Priming is one of techniques to improve the physiological and biochemical efficiency that can enhance seed germination under stressful conditions such as salinity. Therefore, for seeds produced in the years of 2012, 2013 and 2014, three separate experiments were conducted based on completely randomized design with two factors of seed priming and salinity stress. first factor was priming treatme...
to better understand seed priming that improve seed germination and seedling uniformity, we examined the physiological role of osmopriming in germination of bread wheat (triticum aestivum l.) seed embryos by a proteomic approach. for this purpose, we used two systems. the first system consisted of osmo-primed seeds by peg 6000 at -0.8 mpa at 15?c for 24 hours, followed by air drying at 15?c, an...
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Two field experiments in 1993 and 1994 as well as a laboratory germination experiment were conducted on the Egyptian cotton cultivar Giza 75 (Gossypium barbadense) to determine the effect of six concentrations of kinetin (6-furfurylaminopurine) ranging from 0 to 10.0 mg l(-1) and three different methods of application: (A) seeds were soaked for 24 h before germination (laboratory experiment) or...
In order to study the effects of hormone and hydroprimng on seed germination, growth and antioxidant enzymes activity of borage seedling, an experiment was carried out based on completely randomized design with three replications at the University of Mohaghegh Ardabili in 2015. The Experimental treatments were seed priming with gibberellin (50, 100, 150 ppm for 12, 24, 48 hours) and salicylic a...
Objective: To evaluate the effect of chemical stimuli on germination and seedling growth of Caper (Capparis Spinosa) under drought stress. Methods: Factorial experiment in a completely randomized design with four replicates per treatment were performed. First factor of priming include three levels of acetylsalicylic acid (300, 200 and 100 mg/L), gibberellic acid levels (500, 250 and 12...
This experiment was conducted as a factorial experiment based on a completely randomized design with three replications at two locations: Agricultural and natural resource center of Ardebil province (Moghan) and seed and plant certification and registration institute of Karaj in 2013. The treatments included: planting date in three levels (10-May, 25-May and 9-Jun), seed moisture content at har...
Seed priming is the most important technique for increasing the germination power. This study was conducted to investigate the effects of halopriming and hydropriming on improvement of seed germination in black locust (Robinia pseudoacacia L.) in a completely randomized design with 4 replications. Halopriming treatments of KNO3 with concentrations including (100, 250, 500, 750 mM) and hydropr...
